Cold polishing technique of rice finish machining

Abstract

A rice fine processing and cold polishing technique includes a vertical paddy entering silo-a primary screen-a permanent magnet drum-a vibration cleaning screen-a stone removing machine-a main scouring machine-a secondary scouring machine-a fine mesh screen-a gravity paddy slug separator-a first paddy pounder-a second paddy pounder-a third paddy pounder-a rice grading screen-an abrasive finishing machine-a color selector-a rice grading screen-a length grading machine-a vertical silo for finished product-an electric flow scale-a package. The present invention is characterized in that a vertical rice cooling silo used for cooling the temperature of the rice is arranged before the abrasive finishing machine. The present invention changes the defect of the traditional thermal polishing technique. The present invention adopts the mode of combining natural cooling and mechanical cooling, thus greatly improving the cooling effect, increasing the rice yield by 4 percent, greatly reducing the rate of cracked rice and subliming the rice quality not only from the appearance, but also from the inner quality.

Description

technical field [0001] The invention relates to a finishing process in the rice processing process, more specifically a cold polishing process for rice finishing. Background technique [0002] At present, during the finishing process of rice, the temperature of the rice is getting higher and higher due to the friction between the processing machinery (especially the emery roller rice mill, etc.) and the rice. The temperature of the rice is too high during the processing, which damages the rice The internal physical properties of the rice grains make the rice grains soft and brittle. Therefore, in the existing processing process, there is a cooling process in the polishing machine through mechanical air blowing or adding a conveyor belt in front of the polishing machine. However, these mechanical cooling methods The results are not ideal. When the rice comes out of the rice mill, the rice temperature is generally around 45°C. The polishing process in this form is called therm...

[0002] At present, during the finishing process of rice, the temperature of the rice is getting higher and higher due to the friction between the processing machinery (especially the emery roller rice mill, etc.) and the rice. The temperature of the rice is too high during the processing, which damages the rice The internal physical properties of the rice grains make the rice grains soft and brittle. Therefore, in the existing processing process, there is a cooling process in the polishing machine through mechanical air blowing or adding a conveyor belt in front of the polishing machine. However, these mechanical cooling methods The effect is not ideal. When the rice comes out of the rice mill, the rice temperature is generally around 45°C. This form of polishing process is called thermal polishing.

This polishing temperature will affect the rice quality and reduce the rice yield coefficient (the number of kilograms of rice per hundred kilograms of rice)
